A week after I saw the anhinga at the lake, I went back and looked for it. I did not see it anywhere & was disappointed. Then, as I was looking at a turtle, a head popped up in the middle of the pool that is behind the lower spillway steps. Not only was it the anhinga, but it had a nice sized sunfish impaled on its bill.
